Construction & Design:

The Cometic MLS Cylinder Head Gasket is constructed from multiple layers of high-grade stainless steel, providing exceptional tensile strength and the ability to absorb the shearing forces generated between dissimilar materials such as aluminum heads and cast iron blocks. The outer layers are embossed to enhance sealing contact and coated with Viton, a premium fluorocarbon elastomer known for its excellent heat resistance and chemical durability. This coating ensures the gasket maintains a tight seal even under extreme thermal and mechanical loads.

The uncoated stainless steel shim layer in the center allows for precise thickness adjustments to meet specific engine requirements, ensuring optimal compression and sealing performance. This meticulous construction results in a gasket that not only seals effectively but also resists corrosion and deformation over time.
